I have a Cervinis body kit, and I painted the grills red myself.
I haven't really done anything power-wise yet. I have a MAC Tru-Dual exhaust kit with an H-pipe.
The interior, however, I painted myself. I get a lot of compliments from people. Those pics are older though, I'll get updated ones soon.
I also have the dual-halo LED headlights. I'll update pics as I progress!
